OPAL_2007_I734955
An OPAL analysis for charged particle production in gamma+gamma in LEP. Currently uses ChargedFinalState to define the final state particles within the acceptance, the more recent one GammaGammaFinalState would be preferred but I am not able to make it work with the cuts, see the commented parts in the .cc file. I attach a small sample of Pythia events that can used to test the analysis.test-gmgm-hepmc3.hepmc
